Abstract: Artificial intelligence (AI) based computer systems and methods are disclosed for autonomously creating customer service help guides via a graphic user interface (GUI). Computing instructions operating on processor(s) are configured to automatically crawl digital product categorie(s) and create action script(s) derived therefrom. The action script(s) comprise user directive(s) for completing user task(s) on a computing device and software application configured to render a GUI. A natural language understanding (NLU) model associates the action script(s) with text of the user task(s). The action script(s) are tested against completion criteria to output success result(s). An AI model is trained on the action script(s), the text of the user tasks, and the completion criteria. A client device of user may request assistance with a given task, and may render, in response, graphic-and-text display(s) associated with a relevant action script (as determined by the AI model) on a GUI of the client device.

Abstract: A stator core extends along a longitudinal axis and includes a yoke, and a plurality of radially-inwardly projecting teeth separated by intervening slots. A radially innermost portion of each tooth initially includes a pair of legs separated by a recess disposed therebetween. The conventional tooth tips are unformed in the first stage, thereby defining an increased-size slot opening for allowing the insertion of an enlarged stator winding, which has a width (e.g., diameter for a round conductor) substantially equal to the width of the slot itself. In a second processing stage, after the core itself has been manufactured and wound with stator windings, the legs are cold-formed in order to form tooth tips, which define a reduced-size slot opening to provide an improved magnetic flux path and provide a wire retention function. A high slot fill stator design is provided, which allows and enables higher generator efficiencies and output for a given package size.
